CAR-ROOF.

Application filed March 20, 1911. Serial No. 615,732.

To all whom z't may concern:

Be itknown that I, HERMAN Pairs, a citizen of the United States, andresident of Michigan City, county of Laporte, and State of Indiana, haveinvrnted certain new and useful Improvements in Car Roofs, of which thefollowing is a Specification, and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to roofs for freightcars, its object being toprovide a roof frame of great strength. i The invention consists in the.novel features of construction as hereinafter described, and asillustrated in the accompanying drawings, in which- Figure 1 is atransverse section throughthe frame of the car roof, Fig. 2 is a detailplan of the same; Fig. 3 IS a detail in perspective of one of theI-beams of which the carlines a're forn'ied, partially completed; Fig. iis a similar view showing the completed carline; 5 is a detail inperspective of the (:l'l'lllitfSl'lOWllig the end in incomplete form,and Fig. 6 is a sii'nilar view showing the end of the carline ascompleted.

'lheside plates of the roof frame are shown at 10, 11'. The car-lines12, only one ofwhich is shown, are formed of metal I-be..ms preferablyextending continuously from side to side of the car. These car-lineshave their upper flangesdepressed to form seats for-the purlins l3 andthe ridge-pole 14 These depressions are formed by first apcrturing theweb 15 of the beam, as,

shown at 16, the upper side of the aperture.

preferably being a little lower than theun- (lei-face of the top flange17 of the beam. This flange, together with the portion of the web abovethe aperture, is then forced downwardly into the aperture, 'as shown inFig. 4, thereby forming a recess 18 for re ceiving the purlin orridge-pole. This construction provides wide seats for the purlins andridge-pole without materially weakening the carline. The purlins andridge-pole may be of wood, as shown. The beam of which the carline isformed is originally of Specification of-Letters Patent.

greater length than required for. the completed structure. A portion ofone Wing of its top and bottom flanges of its excessive length is cutaway, as shown. at- 19 in Fig. 5. T he end portion ofthe beam is thenfolded laterally on a. line with the end of the cutaway flange 20,asplainly shown in Fig. 6, thereby providing a. flattened ,end 21 forabutting against the inner face of the plate 10 or 11, and a top flange2'2 for resting upon such plate. \Vhen, as shown in Fig. 1, the sideplate is of greater depth than'the car-line, the lower flange 23 of theoverfolded portion of the beam may also-lee cut away. Bolt-holes areformed inthe -,ov 3rfolded portion 21 of the beam, asshowyn, to permitthe carlirie to be secured to-the side plate. By this construction theairline-is provided with an integral flange which rests upon thesideplate of the roof frame and relieves the, securing bolts of shearingstrains. While the inner flanges of the lateral end extension of thebeam are shown as entirely ren'ioved, it is obvious that'as this is donemerely for the purpose of facilitating the bending of the beam, thecutting away may be limited to the immediate proximity of the bend. Theroof frame thus formed .is-sinn le of construction and of great rigidityand strength.

While the I form of beam is preferred for some reasons, flanged beams ofother forms in cross section may be employed in practising theinvention. 1

I claim as my invention- 1. In a air roof.fin con'ibination, a metalcarline comprising an I-beam having its web apertured and its upperflange de- .pressed into the aperture to form a seat for the purlin.

2. In av car roof, in combination, an integral I-beam carline having aplurality of apertures in its web portion and having its upper flangedepressed into such apertures to form purlin seats.
